摘要

A data transmission method includes calculating, by a user equipment (UE), a first message authentication code of first location privacy setting data, sending, by the UE, the first message authentication code and the first location privacy setting data to a data management network element, receiving, by the UE, a second message authentication code from the data management network element, calculating, by the UE, a third message authentication code of the first location privacy setting data, determining, by the UE, that the first location privacy setting data is not tampered with when the second message authentication code is the same as the third message authentication code.

說明書

Step S105: The LMF sends the first message authentication code, the first freshness parameter, and the first location privacy setting data to a V-GMLC. Correspondingly, the V-GMLC receives the first message authentication code, the first freshness parameter, and the first location privacy setting data from the LMF.

When sending the first message authentication code, the first freshness parameter, and the first location privacy setting data to the V-GMLC, the LMF may add the first message authentication code, the first freshness parameter, and the first location privacy setting data to one message, and the message may be, for example, a Ngmlc_UserPrivacy_Set request.

Step S106: The V-GMLC sends the first message authentication code, the first freshness parameter, and the first location privacy setting data to an H-GMLC. Correspondingly, the H-GMLC receives the first message authentication code, the first freshness parameter, and the first location privacy setting data from the V-GMLC.

When sending the first message authentication code, the first freshness parameter, and the first location privacy setting data to the H-GMLC, the V-GMLC may add the first message authentication code, the first freshness parameter, and the first location privacy setting data to one message, and the message may be, for example, a Ngmlc_UserPrivacy_Set request.

Step S107: The H-GMLC sends the first message authentication code, the first freshness parameter, and the first location privacy setting data to the UDM. Correspondingly, the UDM receives the first message authentication code, the first freshness parameter, and the first location privacy setting data from the H-GMLC.
